An "Rx" or prescription is a written order from a licensed healthcare provider, such as a doctor or nurse practitioner, that authorizes a patient to obtain specific medications. This document includes details like the patient's name, the medication name, dosage, and instructions for use. Prescriptions are essential for ensuring that patients receive the correct treatment for their health conditions. Pharmacies use prescriptions to dispense medications safely and accurately. The pharmacist reviews the prescription to confirm its validity and may provide counseling on how to take the medication properly. This process helps prevent medication errors and ensures that patients understand their treatment plans.
